Cognitive entity reference recognition

ABSTRACT

Methods, computer program products, and systems are presented. The methods include, for instance: monitoring one or more message of the conversation between multiple users for an entity reference; detecting the entity reference in a message in the conversation. An entity reference list stores previously established alternate name referring to a user in the conversation. By analyzing the message and following messages in the conversation for relevance of and sentiment to the entity reference, the entity reference is evaluated and if acceptable, the entity reference list is updated with the entity reference as a new alternate name to identify the user in subsequent messages.

TECHNICAL FIELD

The present disclosure relates to cognitive computing technology, and more particularly to methods, computer program products, and systems for recognizing names referring to a certain entity and assisting participants of a conversation with the name-entity associations.

BACKGROUND

In conventional group messenger applications, participants may not recognize alternate names referring to a certain user as some users may use one alternate name and other users may use another alternate name. All participants in a group conversation may not be aware of all nicknames for other participants, which may be made up during the conversation. Accordingly, users need to exchange messages only to identify which name refers to whom during the group conversation.

SUMMARY

The shortcomings of the prior art are overcome, and additional advantages are provided, through the provision, in one aspect, of a method. The method for recognizing a reference to an entity from a conversation includes, for example: monitoring, by one or more processor, one or more message of the conversation between two or more users for an entity reference, wherein the two or more users have respective user profiles including respective user names; detecting the entity reference in a message of the one or more message from the monitoring, the entity reference being not present in an entity reference list, wherein the entity reference list includes zero or more alternate name referring to a user of the two or more users, wherein an alternate name is distinctive from the respective user names; analyzing the message and following messages in the conversation for relevance of the entity reference and sentiment associated with the entity reference; determining that the entity reference is appropriate for later use based on the analyzing and respective thresholds for relevance and sentiment; and updating the entity reference list with the entity reference as a new alternate name for the user such that the user may be identified by use of the new alternate name in subsequent messages.

Additional features are realized through the techniques set forth herein. Other embodiments and aspects, including but not limited to computer program product and system, are described in detail herein and are considered a part of the claimed invention.

DETAILED DESCRIPTION

FIG. 1 depicts a system 100 for cognitive entity reference recognition, in accordance with one or more embodiments set forth herein.

The system 100 includes a user 101, a user device 110, and one or more message in a conversation 105. The conversation 105 is conducted over a telecommunication network amongst one or more group of users, by use of compatible messaging application programs running on respective user devices. The telecommunication network and the messaging application programs are not shown in the system 100, as the conversation 105 may take place by use of conventional telecommunication environments and messaging tools not within the scope of this specification. The user device 110 runs a cognitive entity reference recognition engine 120 that dynamically recognizes references to users/groups from the conversation 105 and presents an entity reference adjusted message 199 to the user 101 for a corresponding message 107 from the one or more message in the conversation 105.

The cognitive entity reference recognition engine 120 includes a response catalogue 130, an entity reference list 140, a query generator 150, a response analyzer 160, and a cognitive entity reference listing process 170. The cognitive entity reference recognition engine 120 may employ various external service utilities including a machine learning process 181, a content analytics process 183, a natural language classification process 185, and a sentiment analysis process 187. The machine learning process 181 may be utilized to create appropriate responses to a preceding message, as trained by actual conversation messages. The content analytics process 183 may be utilized to analyze topics of the conversations, etc. The natural language classification process 185 may be used to classify the messages as well as components of the messages as employed by the query generator 150. The sentiment analysis process 187 may be used to assess sentiments associated with entity references by the response analyzer 160, as used by the cognitive entity reference listing process 170 to evaluate the entity references.

The response catalogue 130 stores messages that may be provided responsive to a preceding message in conversations. The response catalogue 130 may be created by use of, but not limited to, past messages and conversations, various external service utilities including the machine learning process 181 and the content analytics process 183, etc. In certain embodiments of the present invention, a message of the response catalogues 130 may be associated with other responses suitable for the preceding message, respective sentiment associated with each response, the context of the patterns stored in the response catalogue 130, etc.

The entity reference list 140 stores one or more entity names that may be used in displaying the entity names in messages for the user 101. A user may have a registered user name, a chat name configured for each conversation thread, or one nickname used for all conversations, etc., as updated by the cognitive entity reference listing process 170. The entity reference list 140 stores the one or more entity names and display the most relevant name for the participants of the conversation. An exemplary message displays for respective participants in a same conversation is presented in FIG. 3B and corresponding description.

The query generator 150 creates a query upon detecting a new entity reference appearing in the message 107, which is not stored in the entity reference list 140. In this specification, the term “classifier” refers to a group of words that is likely to contain a name for a person. For example, in a message to a user named “Robert” stating “Hi, Bob, how are you doing?”, “Hi/Bob/you/?” is a classifier that includes a greeting “Hi”, followed by an unknown term of address “Bob”, and followed by the second person pronoun “you”, in an interrogative sentence marked by a question mark (?). The classifier “Hi/Bob/you/?” signifies that the unknown term of address “Bob” is likely to indicate the user “Robert” to whom the message is being addressed. Also in this specification, the term “query” refers to an inquiry as to if the alternate reference appearing in the classifier refers to the entity, and includes the classifier, the user, and an alternate reference to the user. In the previous example, the query (Classifier, User, AltName) may be instantiated as (Classifier=hi/Bob/you/?, User=Robert, AltName=Bob), inquiring if “Bob” refers to the user “Robert” by user of the classifier “hi . . . you . . . ?”, to whom the message is being addressed. The query generator 150 may utilize one or more external service utilities, including the content analytics process 183 and the natural language classifier 185, etc.

The response analyzer 160 analyzes contexts of conversations and determines whether or not the new entity reference is proper and relevant within the context of the conversation. Further the response analyzer 160 may utilize external service utilities such as the sentiment analysis process 187 to assess sentiment associated with the response in using the new entity reference.

The cognitive entity reference listing process 170 passively monitors messages of the conversation 105, detects a new entity reference from the messages, and processes the entity reference by coordinating and controlling operations of the query generator 150 and the response analyzer 160, and by utilizing and updating data stored in the response catalogue 130 and the entity reference list 140. Detailed process of the cognitive entity reference listing process 170 is presented in FIG. 2 and corresponding description.

While using messaging services for groups, participants in a group conversation may use various names to refer to one user. The group conversation is ordinarily conducted by use of group chat applications and/or group text messengers. Over time, the names may evolve to other names and if the participants do not follow the group conversation closely, it would be very difficult for such infrequent participants to understand who is talking about whom. Similarly, wherein one user is called by many names, participants of the group conversation may not understand who is addressed by what name, may forget some names while remembering others, etc., and the group conversation may be frequently interrupted due to the inconsistency in the terms of address amongst the participants. Conventional messaging applications uses rudimentary manual setting of one or more chat name, which does not reflect the terms of address for respective users in the ongoing conversation.

Certain embodiments of the present invention dynamically recognizes terms of address associated with entities from conversation messages as entity references based on relevance and semantics of the language, analyzes the sentiment accompanying the entity references, and registers the entity references that are positively accepted for future usage. Further, based on the characterization of the groups, certain alternate names may be further evaluated for the appropriateness. For example, for a group conversation amongst high school friends, rather informal nicknames for one user may be evaluated as acceptable, while the same informal nicknames for the same user may be evaluated as inappropriate for another group conversation amongst work colleagues.

FIG. 2 depicts a flowchart performed by the cognitive entity reference listing process 170 of FIG. 1, in accordance with one or more embodiments set forth herein.

Each of blocks 210 through 250 is a predefined process, in which multiple operations may be performed to achieve respective functionalities. In preparation of running the cognitive entity reference listing process 170, a user profile including user name information had been configured either manually by a user or automatically by the cognitive entity reference recognition engine 120 for each user.

In block 210, the cognitive entity reference listing process 170 monitors messages of a conversation in real-time and detects a new reference to an entity and use contexts of the new reference in a message by analyzing individual messages of the conversation. As entities in the conversation are people and people refer to other people by respective names, the references to entities may be names of participants in the conversation, and may be detected by natural language classification on the subject word, sentence structure analysis as well as part of speech analysis, including but not limited to positions relative to, greetings, punctuations, beginning and/or end of a sentence, etc. If one of the participants in the conversation refers to another participant by using an alternate name other than what is already known to other participants, as stored in the entity reference list 140, the cognitive entity reference listing process 170 may detect such alternate name. A participant may belong to multiple conversation group based on the relationships amongst members of each conversation group, in which the participant may be referred to by distinctive names. For example, a user may have a respective conversation thread with family members who call the user “Eddy”, with colleagues who call the user “Ed”, and with bowling teammates who call the user “Little Ed”, etc. The cognitive entity reference listing process 170 detects the alternate reference as a new reference if the alternate reference is not discovered in the entity reference list 140, in which the new reference would be stored, as resulting from block 250. Exemplary usage of multiple alternate references to one entity is presented in FIG. 3B and corresponding description. Then the cognitive entity reference listing process 170 proceeds with block 220.

In block 220, the cognitive entity reference listing process 170 creates a query for an alternative name detected in block 210 and initiates analysis of subsequent messages in the conversation. The query for the alternate name may include a classifier and additional attributes, including the alternate name and/or usage context of the alternate name. Then the cognitive entity reference listing process 170 proceeds with block 230.

In certain embodiment of the present invention, the cognitive entity reference listing process 170 may create the query based on the context of messages in the conversation, even the alternate name had not been detected in block 210 because the alternate name was not a typical entity reference such as a proper noun and/or other candidate words/phrases. In certain embodiment of the present invention, the classifier of the query may be obtained by an external service utility such as a natural language classifier. For example, a query having a classifier “hey/Rob/you/?” and AltName “Rob” may be created based on a message from Nathan to Robert stating “Hey, Rob, can you call me?” for “User=Robert”. In the same example, the query may further include usage contexts representing circumstances in which the alternative name “Rob” is used for the user “Robert”, such as a specific group of participants in a conversation, a particular user who used a specific alternative name, etc. Accordingly, the query may further include “Attribute:Group=ABC High” as Robert and Nathan are in a group chat titled ABC High, “Attribute:UsedBy=Nathan” as Nathan used the AltName “Rob”, and/or additional alternative name and usage contexts that had been previously detected as an alternative reference to the user Robert and stored in the entity reference list.

In block 230, the cognitive entity reference listing process 170 evaluates the entity reference detected in block 210 based on the subsequent message in the conversation, as analyzed from block 220. Then the cognitive entity reference listing process 170 proceeds with block 240.

In certain embodiments of the present invention, the entity reference may be evaluated for relevance, sentiment, confidence, and combinations thereof, wherein the relevance indicates how accurately the entity reference designates an entity participating in the conversation and conversely may be measured by how accurately the user responds to the message in subsequent messages in the conversation. In the same embodiment of the present invention, the sentiment indicates how positively or negatively the entity reference is perceived by the entity being designated and/or other participants of the conversation, which may be measured by examining how positively or negatively the user responds to the entity reference in the following messages. In the same embodiment of the present invention, the confidence indicates how confident the participants may be on referring the entity by the entity reference based on the number of comparable references. For example, the cognitive entity reference listing process 170 may assign a very high level of confidence on an “AltName=Ed”, or “AltName=Eddy” for “User=Edward”, but would assign a very low level of confidence on an “AltName=Jack” for “User=Edward”, based on the number of entity references in historical data for past conversations. In certain embodiments of the present invention, the cognitive entity reference listing process 170 evaluates the entity reference in two stages, first by relevance and next by sentiment, such that the entity reference may be reasonably accurate in referring to the entity and the reference is reusable as being positively perceived. Exemplary entity reference evaluation is described in FIG. 3A and corresponding description.

In block 240, the cognitive entity reference listing process 170 determines whether or not the new entity reference detected from block 210 is acceptable such that the new entity reference may be reused to refer to the entity in later messages of the same conversation thread as well as other conversations. In certain embodiments of the present invention, the cognitive entity reference listing process 170 may determine the acceptability of the new entity reference by use of, inter alia, a respective range of applicable metric values, respective thresholds for cut-off for each applicable metrics, etc., depending on the methods of evaluation from block 230. For example, if the relevance of the entity reference is quantified as a score during evaluation of block 230, then the acceptability test may be a range of relevance scores. Also in the same example, the relevance of the entity reference may be classified in one of three levels including low, medium, and high, indicating medium to high level of relevance to be acceptable. For another example, if the sentiment of the entity reference is evaluated as one of three categories including positive, neutral, and negative, then acceptability test may be a cut-off for the entity reference associated with a negative sentiment, and the entity reference associated with either positive or neutral sentiment may be acceptable. Sentiments may be evaluated for the new entity reference on the message wherein the new entity reference first appeared, subsequent messages responding to the new entity reference, and/or any comment on the new entity reference within the group conversation, etc. If the cognitive entity reference listing process 170 determines that the new entity reference is acceptable, then the cognitive entity reference listing process 170 proceeds with block 250. If the cognitive entity reference listing process 170 determines that the new entity reference is not acceptable, then the cognitive entity reference listing process 170 concludes processing the new entity reference detected in block 210.

In block 250, the cognitive entity reference listing process 170 updates the entity reference list 140 with the new entity reference such that the new entity reference may be reused to identify the entity as an alternate name, as established in blocks 220 through 240. Exemplary usage of multiple alternate references to one entity is presented in FIG. 3B and corresponding description. The user 101 may manually remove or edit entity references in the entity reference list 140, and/or may turn on and turn off the cognitive entity reference recognition engine 120 on the user device 110. Also the alternate references may be distinctive for respective groups and/or conversations for the same user, and based on analyzing participants and known entity references of the participants, entity references may be transferred from other entity reference lists of the participants. In certain embodiments of the present invention, updated entity reference list 140 may be synchronized with other entity reference lists on user devices of respective participants of the same group conversation. Then the cognitive entity reference listing process 170 concludes processing the new entity reference detected in block 210. The cognitive entity reference listing process 170 iterates blocks 210 through 250 as a unit while passively monitoring messages in conversations.

FIGS. 3A and 3B depict exemplary conversation messages as processed by the cognitive entity reference listing process 170, in accordance with one or more embodiments set forth herein.

Prior to running the cognitive entity reference recognition engine 120 application program, both Robert and Nathan had filled out respective user name information in the respective user profile for the cognitive entity reference recognition engine 120 application program running on the respective user devices. Both users may have configured the respective entity reference lists that catalogues nicknames for people in the conversations. The cognitive reference recognition engine 120 application program may run as an add-on and/or plug-in program for conventional messaging applications.

In the conversation of 301 and 302 of FIG. 3A, Robert and Nathan are participating in a group chat for Group A of close friends. In message 301, Nathan asks if Robert wants to join them in plans for the evening. Boldfaced “Rob” in message 301 indicates a nickname of Robert used in the group chat A. If the cognitive entity reference listing process 170 detects “Rob” in message 301 for the first time, the cognitive entity reference listing process 170 generates a query if “Rob” is a usable nickname for the user “Robert” and proceeds with analyzing message 302 to see how the alternate name “Rob” is responded. In message 302, the cognitive entity reference listing process 170 extracts “Hey”, “Ya”, and “I”, and evaluates the alternate name “Rob” as relevant to “Robert” as well as associated with an positive/neutral sentiment based on “Hey/Ya/I” in a declarative statement, which properly responds to message 301 as if the registered user name “Robert” has been used. Accordingly, the cognitive entity reference listing process 170 updates the entity reference list with the nickname “Attribute:AltName=Rob” for “User=Robert” as “Attribute: UsedBy=Nathan” or “Attribute:UsedBy=Group A”.

Further in the conversation of 311 through 313 of FIG. 3A, Robert and Nathan are exchanging messages, following the conversation of 301 and 302. In message 311, Nathan addresses Robert with a nickname “Rob”, which had been previously registered as above. In message 312, Robert uses a new term of address “Natedog” in responding to message 311 as well as asking another question “Hey/Natedog/yes; Are/you/?”. As in analyzing message 302, the cognitive entity reference listing process 170 detects “Natedog”, generates a query if “Natedog” is a usable nickname for the user “Nathan” and proceeds with analyzing message 313 to see how the new alternate name “Natedog” is responded. In message 313, the cognitive entity reference listing process 170 extracts “Yes”, “you”, and “great”, and evaluates the alternate name “Natedog” as relevant to “Nathan” as well as associated with an positive/neutral sentiment based on “Yes/great” used in a declarative statement, which properly responds to message 312 as if the registered user name “Nathan” has been used. Accordingly, the cognitive entity reference listing process 170 updates the entity reference list with the nickname “Attribute:AltName=Natedog” for “User=Nathan” as “Attribute: UsedBy=Robert”. Further, the cognitive entity reference listing process 170 may be configured to permit all participants in the same group chat to use the nickname in the entity reference list without further evaluation, as the group chat members may share similar recognition and sentiment for the nickname as other participants.

In another conversation having message 320 of FIG. 3B, Robert, Mark, and Jane are exchanging messages, in another group chat for a book club. Jane and Robert are college friends and, because Robert goes by “Rob” amongst the college friends, Jane calls Robert Rob. Mark and Robert are work colleagues, and, because Robert goes by Bob at work, Mark calls Robert Bob. Both nicknames “Rob” and “Bob” are stored in the entity reference list for “Robert” in respective user devices for Jane and Mark. In message 320, Jane is asking Robert a question by calling Robert by one of the nicknames “Rob”. On the user device of Jane, message 320J with the nickname “Rob” is displayed as Jane used. On the user device of Robert, message 320R with the nickname “Rob” is displayed as Jane used such that Robert would know that Jane asked the question. On the user device of Mark, message 320M with the nickname “Bob” is displayed because Mark is not familiar with Robert going by “Rob” and Mark may be confused with the nickname “Rob”.

Certain embodiments of the present invention may offer various technical computing advantages in assisting users, including automated cognitive entity reference detection and customized replacement for respective users in group conversation messages. Multiple terms of address for a user in a group conversation may be stored in an entity reference list on respective user devices and synchronized for participants of the same group conversation such that the recorded entity references would be recognized as nicknames for the user later. A new entity reference would be detected by content analytics and natural language classification of words and/or messages forming a context for the entity reference. The new entity reference is evaluated by relevance, confidence, and sentiment associated with the entity reference such that only a relevant and associated with a positive sentiment would be accepted for repeated usage. Certain embodiments of the present invention improves efficiency and accuracy in identifying one user by numerous alternate names, as well as presents individualized display of alternate names pursuant to familiarity of individual users for respective names. Certain embodiments of the present invention assists participants of a group conversation by preventing confusion as to the association of certain alternate names and respective participants and by preventing repetitive exchange of messages to identify who is referred to by what name, resulting in reduced and more efficient use of network traffics. Certain embodiments of the present invention may be implemented as an add-on or plug-in features of conventional messenger applications such that more focused and efficient cognitive entity reference recognition and processing would be available than in messenger applications with integrated entity reference recognition functionalities.

FIGS. 4-6 depict various aspects of computing, including a computer system and cloud computing, in accordance with one or more aspects set forth herein.

It is understood in advance that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.

Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g. networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.

Characteristics are as follows:

On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.

Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).

Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).

Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.

Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported providing transparency for both the provider and consumer of the utilized service.

Service Models are as follows:

Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.

Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.

Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).

Deployment Models are as follows:

Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.

Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.

Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.

Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds).

A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure comprising a network of interconnected nodes.

Referring now to FIG. 4, a schematic of an example of a computer system/cloud computing node is shown. Cloud computing node 10 is only one example of a suitable cloud computing node and is not intended to suggest any limitation as to the scope of use or functionality of embodiments of the invention described herein. Regardless, cloud computing node 10 is capable of being implemented and/or performing any of the functionality set forth hereinabove.

In cloud computing node 10 there is a computer system 12, which is operational with numerous other general purpose or special purpose computing system environments or configurations. Examples of well-known computing systems, environments, and/or configurations that may be suitable for use with computer system 12 include, but are not limited to, personal computer systems, server computer systems, thin clients, thick clients, hand-held or laptop devices, multiprocessor systems, microprocessor-based systems, set top boxes, programmable consumer electronics, network PCs, minicomputer systems, mainframe computer systems, and distributed cloud computing environments that include any of the above systems or devices, and the like.

Computer system 12 may be described in the general context of computer system-executable instructions, such as program processes, being executed by a computer system. Generally, program processes may include routines, programs, objects, components, logic, data structures, and so on that perform particular tasks or implement particular abstract data types. Computer system 12 may be practiced in distributed cloud computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed cloud computing environment, program processes may be located in both local and remote computer system storage media including memory storage devices.

As shown in FIG. 4, computer system 12 in cloud computing node 10 is shown in the form of a general-purpose computing device. The components of computer system 12 may include, but are not limited to, one or more processors 16, a system memory 28, and a bus 18 that couples various system components including system memory 28 to processor 16.

Bus 18 represents one or more of any of several types of bus structures, including a memory bus or memory controller, a peripheral bus, an accelerated graphics port, and a processor or local bus using any of a variety of bus architectures. By way of example, and not limitation, such architectures include Industry Standard Architecture (ISA) bus, Micro Channel Architecture (MCA) bus, Enhanced ISA (EISA) bus, Video Electronics Standards Association (VESA) local bus, and Peripheral Component Interconnects (PCI) bus.

Computer system 12 typically includes a variety of computer system readable media. Such media may be any available media that is accessible by computer system 12, and it includes both volatile and non-volatile media, removable and non-removable media.

System memory 28 can include computer system readable media in the form of volatile memory, such as random access memory (RAM) 30 and/or cache memory 32. Computer system 12 may further include other removable/non-removable, volatile/non-volatile computer system storage media. By way of example only, storage system 34 can be provided for reading from and writing to a non-removable, non-volatile magnetic media (not shown and typically called a “hard drive”). Although not shown, a magnetic disk drive for reading from and writing to a removable, non-volatile magnetic disk (e.g., a “floppy disk”), and an optical disk drive for reading from or writing to a removable, non-volatile optical disk such as a CD-ROM, DVD-ROM or other optical media can be provided. In such instances, each can be connected to bus 18 by one or more data media interfaces. As will be further depicted and described below, memory 28 may include at least one program product having a set (e.g., at least one) of program processes that are configured to carry out the functions of embodiments of the invention.

One or more program 40, having a set (at least one) of program processes 42, may be stored in memory 28 by way of example, and not limitation, as well as an operating system, one or more application programs, other program processes, and program data. Each of the operating system, one or more application programs, other program processes, and program data or some combination thereof, may include an implementation of the cognitive entity reference recognition engine 120 including the cognitive entity reference listing process 170 of FIG. 1. Program processes 42, as in the cognitive entity reference recognition engine 120 generally carry out the functions and/or methodologies of embodiments of the invention as described herein.

Computer system 12 may also communicate with one or more external devices 14 such as a keyboard, a pointing device, a display 24, etc.; one or more devices that enable a user to interact with computer system 12; and/or any devices (e.g., network card, modem, etc.) that enable computer system 12 to communicate with one or more other computing devices. Such communication can occur via Input/Output (I/O) interfaces 22. Still yet, computer system 12 can communicate with one or more networks such as a local area network (LAN), a general wide area network (WAN), and/or a public network (e.g., the Internet) via network adapter 20. As depicted, network adapter 20 communicates with the other components of computer system 12 via bus 18. It should be understood that although not shown, other hardware and/or software components could be used in conjunction with computer system 12. Examples, include, but are not limited to: microcode, device drivers, redundant processors, external disk drive arrays, RAID systems, tape drives, and data archival storage systems, etc.

Referring now to FIG. 5, illustrative cloud computing environment 50 is depicted. As shown, cloud computing environment 50 comprises one or more cloud computing nodes 10 with which local computing devices used by cloud consumers, such as, for example, personal digital assistant (PDA) or cellular telephone 54A, desktop computer 54B, laptop computer 54C, and/or automobile computer system 54N may communicate.
